RE: Help w Fault codes
code 5868 = The maximum dosing adjustment has been reached. - Aftertreatment 1 SCR Feedback Control Status - Mechanical System Not Responding or Out of Adjustment

5868 is a secondary fault code that is issued when other codes are active. the other fault code is triggering it.

Fault Code: 3749 = An offset in the outlet NOx sensor reading has been detected. (readings have driifted higher than normal).

==============

just some guessing here...
bad sensor? . bad wiring harness?. Failing system?. Aftermarket SCR, DPF, etc?. Program needs an update?. problem with DEF fluid, pump, injector, etc?
